TECHNICAL DATA
PCM CODEC
- FILTER
KK145567N is a one-chip PCM-cofidec which converts speech signal into digital form and backwards. The IC is design to operate in synchronous and asynchronous systems and is prised of:
- reference generator;
- filters on switching capacitors in transmission and receipt channels ;
- two operational amplifiers. The IC does signal panding under the A-low and full differential processing of analogue signals for reduction of noises. Typical dissipated power is 40mW, under reduced power
- 1 mW at ±5 V.
